Central heating system boiler diagram.
This diagram illustrates how simple the heating system connected to a combi boiler is.
Single pipe feed and return micro bore.
The boiler diagram below works by heating the central heating water and pumping it around to the diverter valve.
This is then diverted from the central heating circuit to go into the water to the heat exchanger where it passes the heat from the central heating water to the cold water coming into the boiler.
System boilers are slowly becoming more common.
Central boiler s new forge outdoor coal furnace can be the perfect choice for those that live where coal is abundant and available.
So if it is lashings of hot water at a forceful pressure you are looking for then this is the system for you.
The vented boiler regular boiler and combination boiler systems probably account for over 95 of water based central heating installations.
Built with the same quality and attention to detail as central boiler s outdoor wood furnaces the forge is a better way to heat with coal.
Water central heating the pipework.
You should read this page in conjunction with the page on boilers and the page on heating controls.
Central heating system diagram with high pressure boiler this type of system operates at mains water pressure and uses a stored hot water system.
Effectively the higher the efficiency rating the less fuel the boiler.
The diagrams below show three central heating types.
No external pump no tanks no external expansion vessel no motorised valves and in many cases item 6 is not needed either.
System boilers have a central heating output rating which gives an idea of how many radiators the unit will be capable of heating up.
Boilers convert fuel into usable energy and how much of the fuel ends up being converted is reflected in the efficiency rating.
Conventional boiler this boiler is the most basic type it just burns fuel to make heat for central heating or hot water.
Building regulations always recommends a system filter be fitted to your heating system pipes prior your boiler to prevent any damage to key components.
System boiler this boiler provides central heating only or heating and a store of hot water in a hot water cylinder tank.
